To get the most out of this book

This book is a hands-on guide, with step-by-step instructions on how to work with GraalVM. Throughout the book, the author has used very simple, easy-to-understand code samples that will help you to understand the core concepts of GraalVM. All the code samples are provided in a Git repository. You are expected to have good knowledge of the Java programming language. The book also touches upon Python, JavaScript, Node.js, Ruby, and R – but the examples are intentionally kept simple, for understanding, while focusing on demonstrating the polyglot interoperability concepts.

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
